Step-by-step explanation
Photochemical smog is a type of air pollution that results from the interaction between sunlight and pollutants such as nitrogen oxides and volatile organic compounds (VOCs). This type of smog is common in urban and industrial areas where there is a high concentration of these pollutants.
The conditions favorable for the formation of photochemical smog include strong sunlight, stagnant air, and the presence of pollutants such as those emitted by vehicles and industrial processes.
Given the options:
- Option A : Industrial areas - These typically have a high concentration of pollutants like nitrogen oxides and VOCs that can interact with sunlight to form photochemical smog.
- Option B : Himalayan villages in winter - Likely to have less sunlight and fewer pollutants.
- Option C : The places with healthy vegetation - Vegetation can actually help to reduce smog by absorbing pollutants.
- Option D : Marshy lands - Unlikely to have the concentration of pollutants necessary for photochemical smog formation.
The correct answer is : Option A : Industrial areas.
